One can imagine a computer simulation of the action of peptides in the hypothalamus that is accurate down to the last synapse. But... equally one can imagine a computer simulation of the oxidation of hydrocarbons in a car engine or the action of digestive processes in a stomach when it is digesting pizza. And the simulation is no more the real thing in the case of the brain than it is in the case of the car or the stomach. Barring miracles, you could not run your car by doing a computer simulation of the oxidation of gasoline, and you could not digest pizza by running the program that simulates such digestion. It seems obvious that a simulation of cognition will similarly not produce the effects of the neurobiology of cognition.LESSATTRIBUTION DETAIL »

Your brain receives, stores, and processes information, dispenses results, and controls your biological equipment. When properly p...rogrammed, computers can do likewise, except that they control electromechanical rather than biological equipment. Beyond these functional similarities, computers and brains have virtually nothing in common. To begin with, the electronic circuits in a computer are not analogous to brain cells. The two differ in appearance, in structure, and in principles of operation. The key functions of information storage and information processing are served in computers by physically different components. In a typical computer, one finds separate CPU and memory units; but even in computer designs where processing circuits are intermixed, the two functions remain distinct. In the brain they are not distinct; they're distributed throughout the brain and intermixed in ways that we don't understand.LESSATTRIBUTION DETAIL »

What, then, is the basic difference between today's computer and an intelligent being? It is that the computer can be made to see ...but not to perceive. What matters here is not that the computer is without consciousness but that thus far it is incapable of the spontaneous grasp of pattern--a capacity essential to perception and intelligence.LESSATTRIBUTION DETAIL »

A computer does not think, it feels nothing, and what it is said to "know"--bits of information all cast in the digital mode--has ...no fringe. Nor has it a memory, only storage room. On any point called for, the answer is all or none. Vagueness, intelligent confusion, original punning on words or ideas never occur, the internal hookups being unchangeable; they were determined once for all by the true minds that made the machine and program. When plugged in, the least elaborate computer can be relied on to work to the fullest extent of its capacity; the greatest mind cannot be relied on for the simplest thing; its variability is its superiority.LESSATTRIBUTION DETAIL »

Computer science only indicates the retrospective omnipotence of our technologies. In other words, an infinite capacity to process... data (but only data--i.e. the already given) and in no sense a new vision. With that science, we are entering an era of exhaustivity, which is also an era of exhaustion.LESSATTRIBUTION DETAIL »

Query: Whether the difference between a mere computer and a man of science be not, that the one computes on principles clearly con...ceived, and by rules evidently demonstrated, whereas the other doth not?LESSATTRIBUTION DETAIL »

Most of the brain consists of "wires"; a single unit may have thousands of connections with other units and with itself. That is n...ot the case in a standard computer, where a chip usually has less than six connections. Moreover, neurons are much, much slower than the switching elements of the computer. It seems likely that the brain can accomplish its complex feats of perception and thought by means of millions of connections acting in parallel. The connections as a whole define the information content of the system. In this way a vast amount of knowledge can be brought to bear on a decision all at once. The brain seems to be able to perform as many as two hundred trillion operations in a second; not serially, but simultaneously.LESSATTRIBUTION DETAIL »

The child receives data through the sense organs; the child also has some inborn processing capacities--otherwise it would not be ...able to learn--but in addition, some "information" or "programs" are built-in at birth (for example, the child does not have to learn how to suck, for this is an innate reflex); there is a working memory, in which the child keeps those items of knowledge that are being used at a particular moment; and there is a permanent memory, which is, in Locke's terms, largely a "blank tablet" at birth, but which has a storage capacity that makes a hard disk pale into insignificance. The child gradually builds up a symbolic representation of the world around it, so there must be some inner "language" or medium of representation; even a newborn baby is starting to see and taste and smell and hear and touch, and to remember the more striking of its experiences, so the internal medium by which it represents and stores these impressions cannot be the native language (of which it is still ignorant. Jerry Fodor [in The Language of Thought] has discussed this inbuilt "language of thought," which is similar conceptually to the "machine language" that is built into the personal computer and about which most users remain completely ignorant).LESSATTRIBUTION DETAIL »

The language of the game is interesting. You can think of the pauses as caesuras, breaks between the lines. As a poem the game is ...composed of a number of short lines representing the pitches. The number of lines per batter form a stanza. Then there is a space. Sometimes the stanzas become breathless, rushing full paragraphs that build rapidly on each other until the poem-inning explodes. The poem lives for this sudden blossoming out of prosodic regularity. Should someone make a computer analysis of baseball prosody, I believe that they would come up with something close to the prosody of some great American lyrical epic, Whitman's Leaves of Grass, let's say, or Doc Williams's Patterson.... The game is definitely an epic ... formed of many lyrical moments dependent on silences for their effectiveness. An unfolding story punctuated by brief emotional swellings.LESSATTRIBUTION DETAIL »
